LUBRICATOR WITH SUPPLEMENTARY DELIVERIES.

To all whom it may concern:

Be it known that I, JEAN NEPouUoENE HooHGEsANn, of 200 Quai J emmapes, in the city of Paris, Republic of France, engineer, have invented a Lubricator with Supplementary Deliveries, of which the following is a full, clear, and exact description.

The present invention relates to an arrangement for regulating delivery, applicable more particularly to lubricators, and enabling the position of the rod regulating the flow to be known at a distance or at night by the touch. 5% My arrangement of apparatus is characterized particularly by the fact that the'rod regulating the flow carries a rocking button capable of occupying an inclined position, thus permitting an extra [low in excess of the normal flow without altering the regulation previously established, and constituting-besides an indicating means; in ordinary lubricators with means for regulating the flow, it is not possible to know at a distance whether the rod regulating the How is in the position of normal delivery or in a position giving an increased delivery, for when the lubricator is in use the operating button is always upright and it is impossible to ascertain whether it is more or less raised. On the contrary with the apparatus herein described, if the button is vertical it is certain that the lubricator is working with its normal delivery, and if it is inclined, one is aware that the lubricator is giving an extra flow. In order that the button may be retained in an inclined position, the seat upon which it rests has a groove passing across the axis of the rod regulating the flow, and in which the edge of the lower part of the button engages.

My invention further relates to the method of mounting the needle valve; this latter is mounted upon a spiral spring attached to the end of the regulating rod. By means of this elastic mounting, the needle valve is always applied exactly to its seat; further, this arrangement assures a perfect control of the needle valve by the regulating rod and enables all the parts constituting this regulating rod to be mounted and dismounted very easily.

In order that the invention may be more clearly understood, I have shown in the accompanying drawings my new regulating arrangement, by way of exam le only:

of my regulating arrangement to a lubricator of any system whatever, the operating button being in the vertical position corresponding to normal delivery. Fig. 2 is a horizontal section on the line A-B of Fig. 1. Figs. 3, 4 and 5, show di'llerent positions of the operating button, corresponding respectively to the two supplemental deliveries and to the closure of the valve. Fig. 6 shows a modification enabling in addition a very much increased delivery to be obtained. Fig. 7 is a horizontal section on the line CD of Fig. 6. Fig. 8 shows another modification of my invention. Fig. 9 are detail views showing an elevation, a vertical section, and a plan, of the operatingbutton. Fig. 10 shows the various parts of the regulating rod separately. Fig. 11 shows a vertical section and an upper side view of the regulating nut acting as a seat for the operating button. Fig. 12 is a vertical section of the upper part of the cylindrical body which incloses the regulating rod, taken on a plane at right angles to that of Fig. 1.

In these figures the same letters of reference indicate like parts.

As shown in the drawings, the rod a regu lating the flow, carries at its upper part a button I) which is movable on an axis 0 so that it may assume a horizontal position when the apparatus is shut off, a vertical position when the apparatus is giving a normal delivery, and an inclined position when the apparatus is furnishing a greater delivery than usual. The seat d upon which the operating button rests has one or more notches c passing across the axis of the regulating rod a, as shown in Figs. 2 and 11, destined to receive the edge of the base of the button I) when this latter is inclined and to maintain it in this osition.

The button I) may be inclined in two directions so as to give two supplementary delivcries of different quantities; the base of this button has a flat I) cut on one of its sides, as shown in Fig. 9; thus if the button I) is inclined as shown in Fig. 3, so that the lower edge of the flat b engages in the notch (a, a supplemental raising of the needle vtlve is obtained which is less than when the button I) is inclined in the opposite direction and the edge of the base of the button I) is engaged in the notch e as shown in Fig. 4.

In order that the two sides of the button supplemental decorresponding to the two distinguished, the

liveries may be easily head of the button I) has a flat 6 cut on the same side as the flat 6, see Fig. 9.

The base of the button 6 may have on each side a bevel b b", as shown in Fig. 8, which rests upon the seat at when the button is inclined and which will retain it in this position; in this case it will not be necessary to form the seat d with notches or grooves 6.

According to my invention the button 6 therefore occupies different positions, very easy to be distinguished from a distance or bythe touch, according to whether the apparatus is in the shut-off position, the normal position, or the lesser or greater of the supplemental delivery positions. If the button I) is placed horizontally (Fig. 5) the needle f is pressed to its seatand the apparatus is shut off. If the button 6 is placed vertically (Fig. 1) one can readily see that the apparatus is furnishing the normal delivery. On the contrary, if the button I) is inclined to one side or the other, one is notified that the apparatus is allowing a greater delivery than the normal, as above described. The seat (1 may have a raised portion 61 as shown in Figs. 6 and 7, enabling the button I) to be maintained in a raised position, so as to obtain a much greater delivery.

The needle valve f is mounted upon the regulating rod (1 by means of a spring 9 so as to possess an elasticity sufficient to enableit to seat itself accurately; this needle valve f is fixed on one of the ends of the spring 9 as shown in Fig. 10, and this latter is secured on to the threaded end a of the rod a.

The regulating rod a has a sleeve 7b which rests at one end against the spring 9 and the other end of which is acted upon by the closing spring i of the regulating rod, which spring bears at its other end against the interior face of the seat (1.

The sleeve it has a notch 71. as shown in Fig. 10, which acts to grip, when a rotative motion is imparted to this sleeve, the end of the spring 9 and permits the latter to be unscrewed from the rod a without difficulty.

The spring g has for its object to connect the needle f to the rod a; to retain together the different parts constituting the regulating rod without the necessity of a pin or nut to prevent by its own character any accidental unscrewing; to obtain a regulating rod with a flexible end so as to cause the needle valve to seat itself perfectly and consequently to obtain complete closure when the apparatus is shut off.

The regulation of the normal delivery may be controlled by any of the ordinary and convenient methods; for example, by screwing or unscrewing the nut 01 the upper part (1 of which forms the seat for the operatlng button, upon the screw-threaded cylindrical body which incloses the regulating rod. In order to obtain perfect control of this nut 61 and to avoid the use of the lock-nut, the cylindrical body is split at 7', as shown in Fig. 12, so as to form two parts slightly sprung apart and which by their elasticity prevent any accidental unscrewing of the nut (Z The head of this latter is provided with two flat surfaces which enable it to be easily operated by hand or by means of a key.

My invention is applicable to all kinds of lubricators and the forms and details may be varied according to the different uses to which it may be applied.
